???? The plunger is made of steel...Go ahead and clean away... The hole point of removing it is to remove carbon from the passages and the IAC. Cleaned tons of them that way.

todd you are correct, however there is electronics behind the plunger and pushing in and out on the plunger too hard could cause damage to the electronics thus destroying the IAC.
